  I can't seem to find the event that is fired when the Title Bar of a RadForm is double clicked.
  My form is maximized at all times and I don't want the user to change the size of the windown by double clicking the title bar. Form should always stay at maximized state and this (this.WindowState = System.Windows.Forms.FormWindowState.Maximized) is not preventing the resize on Title Bar double click.
  
   MaximizeBox property is set to False to prevent the user from clicking the form's maximize button. This part is working fine.

  Hi Adrian,

  Thank you for writing.
  
  Please consider the following code snippet:
  

  const Int32 HTCAPTION = 0x2;

  const Int32 WM_NCLBUTTONDBLCLK = 0xA3;

   

  protected override void WndProc(ref Message msg)

  {

    switch (msg.Msg)

    {

      case WM_NCLBUTTONDBLCLK:

        if (msg.WParam.ToInt32() == HTCAPTION)

          return;

        break;

    }

    base.WndProc(ref msg);

  }

  
  You have to add these constants and the method to your form.
  
  I hope this will help. If you have further questions, feel free to ask.
